Description
Newly developed Multi-IO connector module, The Fujitsu Multi-IO microGiGaCN™ series product
supports high speed signal transmission in compact package and easy to install structure. This series of
modules incorporates Fujitsu’s world standard high-speed differential 4 channel IO socket interface which
is defined by SFF 8470, InfiniBand™, 10G Base-CX4, and 10G Fiber Channel. The module is designed to
meet InfiniBand DDR, along with the previously mentioned industry standards, in a 4channel, bi-directional
data transfer mode. The Multi-IO connector module allows for increased I/O port density, while allowing for
ease of signal routing on the main pcb.
The Multi-IO microGiGaCN™ product makes it possible to install multiple modules within a small
area with ease of installation with specially designed board to board high speed connector system. The
original concept for the design is to accommodate 20 ports in a IU form factor. This series of module has
capability to accommodate LED link status indicator and MDC (media detect circuitry, connector detect and
power supply circuitry) for Fujitsu’s o-microGiGaCN™ four channel optical transceiver module, which
extends transmission length up to 300 (2.5Gbps) over optic fiber. Future versions of module on
development roadmap (1x4 scheduled) will allow users to select the most suitable ones for their
applications. The die cast backshells provide firm and robust mechanical connection.

Future applications will include 1x4, 1x2, and low profile 2x2 with and without AC blocking caps, LED’s, etc.
Features
• Full compatibility with following world industrial standards.
InfiniBand™, InfiniBand ™ DDR, 10G Fiber Channel, 10G Base-CX4, SFF-8470, etc.
• Four 4x links per module with 2x2 arrangement
• Allows up to twenty 4x links in 1U form factor on single pcb
• Well controlled signal integrity available for DDR signal rate (5Gbps)
• Easy to install structure with high speed board to board interface connector
• Options for Link status LED’s, power line for Fujitsu o-microGiGaCN™ four channel optical
transceiver module (consult factory)
